The first consideration is lumbar disc herniation, which is mainly manifested as lumbar discomfort and sciatica, mainly manifested as numbness and pain radiating along the back of the thigh, calf and back of the foot, and usually requires a lumbar spine CT examination for identification. The lumbar disc herniation is afraid of sedentary, appropriate activities of the waist, but also to avoid strenuous exercise, do not sit for a long time, bend over to hold heavy objects, carry heavy objects, etc., try to lie down, lumbar preheat. If sedentary for a long time, it will inevitably increase the symptoms of lumbar pain and leg numbness. At present, it is recommended that patients lie on a hard bed and preheat the lumbar region, and also use hot water bags for hot compresses, baking electricity and physiotherapy. If the pain is severe, take oral lumbar pain and nerve-nourishing adenosine cobalamin tablets. Generally, the symptoms will be reduced to disappear through strict bed rest for about ten days. If symptoms recur or are not relieved by treatment and there are symptoms of nerve compression, interventional surgery may be sought.
